1 Claim.

This invention relates to improvements in mounting devices.

In its more general application the invention relates to folders suitable for the convenient and attractive mounting, protection and display of photographic and other prints, including etchings, engravings and the like sheet-form objects of artistic or personal interest, or of educational, historical or sentimental nature.

It will be herein described as it may be applied in the field of portrait photography, for which it provides a setting which is fit for portraits of distinction.

Folders for these purposes should not fail to provide the requisite simple atmosphere which gives opportunity for the artistry of the photographer and the attributes of the subject to have their full expression; but they must also serve the utilitarian purposes of affording strong and durable protection and support for the mounted subject. These may include, for some, the ability to survive many individual handlings, and for others a sufficient rigidity to stand edgewise for display when set on edge in partly open state. And sentiment may require them to be capable of preserving their contents over periods of many years, with sturdy durability.

It is among the objects of the present invention to provide these utilities in a folder which may have distinctive aesthetic simplicity and beauty, to endure indefinitely.

The folder of the invention has a three-part structure, of front and back covers, with stout flexible fabric hinge between them. Combined with these covers, which may be relatively stiff, are folded sheets of paper each of which constitutes, for its own particular cover, both a covering or interior lining for the cover, and a secure interior part of the ensemble, the one being a mounting sheet bearing the portrait print, and the other being a fly-leaf for it.

It is an important feature that my'improved mounting folder can be produced at a cost commercially favorable to its extensive sale and use.

To attain these objects and results the two similar sheets of stiff paper board which are to constitute the cover may be connected together by a suitably flexible and strong hinge material, preferably a woven fabric, which may be adhered to the adjacent marginal edges of the two stiff sheets; and this is provided in duplicate, one of the duplicates providing an exterior face, and the other providing an interior face, and the two together making a finished flexible joinder between the two said stiff sheets. The exterior face of each stiff sheet preferably will be surfaced by a thinner sheet of high quality and attractive paper; covering substantially the whole surface, and'bent around all of the edges, except where on the hinge edge it may overlap slightly the hinge 5 material thus making a finished line at this place. This facing paper, adhering at the margin on the inside face, produces rounded edges of the covers.

If a silver coated or other decorative material has been chosen for the hinge fabric, the two straight edges of the papers covering the raw edges of that fabric leave at the hinge edge a decorative line of silver or whatever shall have been chosen, of substantial breadth.

This fabric serves also as a spacer to set the covers in a spaced relation to each other adequate to receive between the two covers the thickness of the portrait sheet or whatever is to be mounted, in the folder. Interiorly, the cover boards are likewise separated by a binding strip of flexible hinge material, preferably like that used for the exterior of the hinge, which adheres along the adjacent margins of the inner faces of the covers.

First, the top and bottom end portions of the exterior binding and hinge member are turned over the tops and bottoms respectively, of the boards, and made to adhere within; and then all but the edge margin of each of these turned-over portions is covered by the interior binding hinge members. The vertical edge portions of the latter are in turn covered by the interior paper elements, whose folded edges leave exposed interiorly, between them, a narrow width of the hinge material. This being equal in width to the space between the cover boards, a decorative spacing hinge of silver covered fabric or other chosen material stands exposed in the interior of the folder.

The inner face of each board is covered with one half of a folded sheet, Whose fold registers about even with that edge of the board where the hinge is, and covers the edge of the interior layer of hinge material. The other parts of these folded sheets constitute respectively, a fly-leaf, and the sheet which is to carry the print, etching or 5 any article mounted thereon. Both of these are in the nature of fly leaves, each being fast to a cover. at a fold, and being free to turn as a leaf. That which is on the back is preferably thicker than the other, and is of material stout enough to carry the mount; and the portion which is to receive the mount may carry a decorative marginal line, or may have other matter printed upon it, to cooperate with the exposed part of the binding hinge so as to produce a dignified and finished setting, in which the portrait may be set by adhesion or in any suitable way. Or, in a suitable case, this mounting fiy leaf may be the sheet on which the portrait is chemically printed. In that case it is a part of the same sheet or an integral extension of that sheet, on the other side of its fold, which covers the inner page of the back cover. In either event the repeated opening and closing of the folder produces no crack or breach of the sheet on which the portrait is mounted.

Thus the print is protected between stout covers, has a fiy-leaf at its face, and is itself on a sheet which can turn on its folding attachment tothe back cover.

It is intended that the patent shall cover by suitable expression in the appended claim whatever features of patentable novelty exist in the invention disclosed.

In the accompanying drawing:

Figure 1 is a perspective of a mounting device embodying features of the invention;

Figure 2 is a section on 2-2 of Figure 1; and

Figure 3 is an elevation of details of a fragment in the region of the lower portion of the hinge, with portions broken away, and other portions partially unlaid, for clearness.

Referring to the drawing, my improved mounting device comprises the two cover sections, [0, I2, which are hinged together at 20, each being of suitably stiff paper board, and each being covered on its interior face with a paper having a fold beyond which is a leaf in the nature of a fly-leaf M or iii. The one of these attached to the rear cover is the sheet on whose face the portrait or other matter may be directly mounted.

Figures 2 and 3 disclose each cover as made up of a base sheet A8 of stiff material, such as paper board or the like, and these two boards are embraced between the two strips 22 and 24, which together constitute the hinge 20, and which may be made of flexible and strong material, preferably of Woven fabric, having any decorative or plain characteristics that may be chosen. One of these fabric strips 22 is laid exteriorly along the adjacent edges of the cover boards l8, and adhering to their margins, and the other is arranged interiorly in like manner and similarly secured, the boards themselves being arranged in positions which are slightly spaced apart, according to the thickness which it is desired to provide interiorly for receiving whatever is to be mounted, as well as providing for the thickness of the interior leaves. One of these strips, preferably the exterior strip 22, has extra length so that it can be bent over the edge, at top and at bottom, to the interior where its laps adhere to the board for a short marginal distance, and are covered by the other strip 24 which extends upward and downward, and terminates with a finished edge close to the top and bottom respectively, as at 26 in Figure 3.

The exterior face of each board I8 is covered with a thin sheet 28 of good quality paper, whose margins are bent over the edges to the inside face of the board at top and bottom and free edge, while at the outer hinge edge the facing sheet overlaps slightly the hinge material and provides a straight finished edge, as seen respectively at 29, in Figure 3, and under the reference number 20, Figure 2.

Interiorly each of the boards l8 has a facing sheet covering the interior face of the board and covering also the infolded flaps of the exterior facing sheet 28. The cover section l0 may have its interior facing 30 of paper stock of such good quality or characteristic as is desired to face the portrait; and this interior facing sheet has a crease or fold l5 which preferably is located so that it has the board l8 underlying it, along the edge of the board, and thence continues loosely as a fly-leaf M.

The other cover section l2 similarly has interiorly at 32, a facing sheet which has a crease or fold l5, whence it continues loosely to provide the mounting leaf [6, being preferably of stock suitable for that purpose, which will usually be heavier and stiffer than stock for the facing 36 and fiyleaf I 4.

The crease I5 being supported on the board, and the providing of a tough fabric hinge which has a clear small flexible width exposed between the boards, without the fly leaves being shaped into the binding, causes practically all of the bending, during use. of the device, to occur in the fabric hinge, and on the one hand provides ample thickness of space in case of the mounting of a thick object in the device, and on the other hand relieves the mounting sheet of having to endure any considerable frequency of bending, and permits it to be of material of any desired delicacy, in case of a printing of the portrait directly on that sheet. Thus the structure is fitted for giving a long and serviceable life in spite of numerous handlings.

I claim as my invention:

A device for the mounting, protection and display of photographic prints and other sheet form objects, comprising the combination of a pair of stiff cover sections; a pair of flexible strips, constituting a duplex hinge; a pair of facing sheets for the cover exteriors; and a pair of lining sheets for the cover interiors; combined with at least one interior sheet for carrying the print, secured on one of the covers and protected by those covers; the whole being organized with the marginal longitudinal portions of the duplex flexible strips adhesively encasing stiff edges of the covers, in parallelism at a distance of edges apart which only slightly exceeds the combined thickness of the two covers, while the middle longitudinal portions of those strips hinge those covers together and constitute. exteriorly and interiorly exposed finish surfaces; with the said facing sheets bordering the said exteriorly exposed finish-strip surface, covering the margins of that exterior strip, and being infolded around the three other stiff edges of the covers, enclosing them and lying inward over the interior margins of those covers at those edges; and with the said linings covering the infolded margins of those facing sheets, and covering the margins of the interior hinge strip; the said interior print-carrying sheet being a folded extension of one of these lining sheets having its fold visibly overlying the margin of the interior finish strip of the duplex hinge.
